Let's just say that if you thought Google or Microsoft know a lot about you, they don't hold a candle to Amazon.
I block anything Micro$oft that I know of at the network level. I have zero interest in any of their online services, and deff no interest/want in anything beyond Windows 8.
To me Micro$oft is probably the worst one out there, with Google a close second.
Google I have to put up with some since my phone is Android, and I use YouTube (both for posting & watching vid's)...that said, I do block some of their spy/ad servers.
I'll never infect any of my computers with that vile-spyware-laden Chrome browser.
I also delete or disable all un-necessary apps on my tablets & phones (no do I install anything unless i really want it - like a certain weather app)
And Mac-In-Trash (also known as Apple)... don't believe that crap ain't spying on you!
I don't do Amazon. Most stuff I buy online is eBay. (And for general stuff that's available locally, I prefer to just go to the store...)
I also don't do Facebook/Twitter/Instagram/TicToc(the very worst of the lot)/etc/whatever else 'social media' is out there.

Oh and I'm fine with 'smart' devices (I have a smart-TV for example)...as long as they will function normally without being connected to the internet.
